harsh environments Product Photo Here Description: Each ratiometric linear Hall-effect sensor contains a monolithic integrated circuit on a single chip. This circuit incorporates a quadratic Hall sensing element, which minimizes the effects of mechanical and thermal stress on the Hall element and temperature compensating circuitry to compensate for the inherent Hall element sensitivity change over temperature current. These ratiometric linear Hall-effect sensors provide an output voltage that varies in proportion to the applied magnetic field. The voltage output will increase in response to a south pole (positive) magnetic field applied perpendicular to the package symbolization face, and will decrease in response to a north pole (negative) magnetic field. These 3150U & 3151U ratiometric linear Hall-effect sensors can be used as a non-contact sensor for rotary and linear position sensing and for current sensing. The devices in this series are similar in performance, except for their allowable quiescent voltage output change over the specified operating temperature range. Applications: • Non-Contact Magnetic Sensing • Assembly LIne Automation • Machine Automation • Machine Safety • Door Sensor • Where sensing is required in dirty environments Qual Hall Element Voltage Regulator Dual to Single Converter 1 Vcc Vcc 3 Output 2 Gnd OHN3150U OHS3150U OHN3151U OHS3151U Ordering Information -20°C to +85°C -40°C to +150°C VOQ Change over TA = ±35 Gauss -20°C to +85°C -40°C to +150°C VOQ Change over TA = ±50 Gauss RoHS OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.
